Direct read-out of transit time of ultrasonics in concrete with
ultrasonic transducers, which is pulsed by high voltage. With the combinations of hogh-energy pulser, high sensitivity receiver and high efficiency transducers, it is excellent in thick and attenuative materials. Compact design makes it easy to operate in work-site or laboratory. LED back-lit enables to read the LCD clearly in dark places. Ni-MH rechargeable battery enables rapid recharge and long time operation. Displays the transit time in 0.1¥ìs unit. Conforms to BS1881 part 203. The X-TranTM connector in main body protects the instrument from damage by connection mistake. Rugged Aluminium case and protective carrying pouch. Low Battery status display. The velocity of ultrasonics, travelling in concrete or wood, depends on its density and elastic stiffness. Contester-1000 generates ultrasonic in a transducer by high voltage, and this energy travels the material and reaches to receiving transducer. When its density and elastic stiffness are high, the transit time is short. On the other hand, when its density and elastic stiffness are low, it takes a longer time. With Contester-1000, it is possible to evaluate materials by non-destructive testing and measure the elastic property by counting a transit time of ultrasonics. Contester-1000 is supplied with 52 kHz ultrasonic transducers, which is manufactured by Q-see man. It was designed to send and receive ultrasonic signals effectively even in high attenuative material, like concrete, wood, stone, brick and plastics. Besides, Contester-1000 used X-TranTM connectors, which protects the instrument from damage by connecting wrongly by mistake. And simple design and functions enable to operate it easily in work-site and laboratory. Contester-1000 was developed by cooperative research with KRISS (Korea Research Institute of Standard & Science), subsidized from the national coffers of Ministry of Science and Technology, one of "Disaster Prevention Technique Development Program". |
